[R] getting a windows environment variable in r

[Bob Sandefur]

hi-
 I would like to get a value set with the dos set command (e.g. set dog=cow) in a rterm session on rterm 1011 under windows 2000. if I try in a dos window:
set dog=cow
echo %dog%
i get cow (what I want)
then i start rterm
system("echo %dog%",intern=T)
gives "%dog%"

I can of course do something like
set dog=cow
echo  %dog% >jnk.rin
and  then start rterm and
jnk<-read.table("jnk.rin")
wantthis<-as.character(V1[1])
wantthis now has what I want

Are there simpler methods?

thanx

Bob Sandefur
